Abstract: Systems and methods for improved surgical planning are disclosed herein. A processor may determine an optimized planning group based on planning group definitions and historical surgeon data through the use of a machine learning classification algorithm. The processor may further receive patient data comprising anatomical landmarks and surfaces, pre-operative deformity measurements, range of motion measurements, and gap data. The processor may generate optimized implant parameters based on the optimized planning group and the patient data using a machine learning model. The optimized implant parameters may include size, position, and orientation parameters for each of a femoral implant and a tibial implant. The processor may further generate a surgical plan based on the optimized implant parameters.

Abstract: A system for tracking resection planes during a surgical procedure includes a cutting block and a position tracker. The cutting block is configured to be mounted on an anterior surface of a bone during the surgical procedure. The cutting block comprises at least one slot configured to position a resection tool during the surgical procedure. The position tracker is configured to be directly attached to the cutting block after the cutting block is mounted on the anterior surface to allow positional tracking of the cutting block by a tracking device during the surgical procedure.

Abstract: A method and system for updating a bone model for a surgical procedure is provided. The computer system can include a display screen for displaying a GUI that allows a user to define one or more shapes to generate a selected volume of a bone model. The computer system can update the bone model to remove the selected volume as defined by the user. The computer system can display the updated bone model to the user and/or use the updated bone model to guide the surgeon to remove the portions of the patient's bone corresponding to the updated bone model under robotic assistance.

Abstract: The present disclosure describes techniques and systems to adapt an arthroplasty system to particular users based on historical arthroplasty procedures associated with the user. Furthermore, the present disclosure provides that settings for an arthroplasty system associated with a user during multiple arthroplasty procedures can be captures. A ML model can be trained to infer settings for subsequent arthroplasty procedures for the user and the arthroplasty system adapted based on the inferred settings.

Abstract: Surgical punch tools and methods of using the same are disclosed herein. A surgical punch tool may include a stationary base component having a planar bottom side. The planar bottom side may include one or more posts extending therefrom. Each post may include an associated sharp pin. A movable actuation portion may be configured to move each sharp pin from a non-actuated position within the corresponding post to an actuated position extending through the base component and from the corresponding post.

Abstract: A surgical robotic arm (520) for use with an external vision system (512) includes onboard control and at least four degrees of articulation. The robotic arm (520) can position various tools (534) in the surgical theatre responsive to positional feedback In from the vision system (512). Exemplary tools (534) include a handpiece (519) that includes a motorized bun or saw, a cutting guide (542) for a handheld saw, or a laser to actively define a resection area for a surgeon. The tool (534) or a reference point on the arm (520) relative to the tool (534) includes fiducial marks to register the position of the tool (534) with the vision system (512). Exemplary (534) are especially suited for knee and hip arthroplasty and can be moved under processor or manual control.

Abstract: A method of placing a ligament graft in a surgical procedure is described. A surgical system receives kinematic information related to a range of motion of a knee joint and registers one or more surfaces of a bony anatomy of the knee joint. The surgical system further generates a three-dimensional model of the knee joint. The surgical system determines a surgical plan including parameters of a graft tunnel based on the kinematic information and the three-dimensional model. A graft tunnel planning system is also described. A plurality of tracking markers are affixed to the patient's bones and a tracking unit captures their location through a range of motion of the patient's knee joint. A point probe captures the geometry of a bony surface of the patient. A computing module receives the location data and geometry data, and determines a surgical plan including parameters of a graft tunnel.
